ORGAN.

SPECIFICATION forming part of Letters Patent No. 502,050, dated July 25,1893.

Serial No. 428.820- (No model.)

To a, whom it may concern.-

Be it known that I, HENRY NELsoN, of Fort Wayne, in the county of Allenand State of Indiana, have invented a new and useful Im' provement inOrgans, of which the following is a full, clear, and exact description.

The invention relates to reed organs, and its object is to providecertain new and useful improvements in organs whereby the tone of eachreed can be readily changed, at the will of the operator, from a soft,fine violetta tone to a clear pipe tone, or to a full, strong, reedorgan tone.

The invention consists of certain parts and details and combinations, ofthe same, as will be hereinafter described and then pointed out in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a transverse section of the improvement. Fig. 2 is a frontView of the same with parts in section on the line 22 of Fig. 1; andFig. 3 is a perspective view of the improvement with the valves removed.

The organ is provided with the usual soundboard A, provided with anopening 13, connected in the usual manner with the suction bellows.Above the aperture B on the soundboard Ais arranged the reed cell G,containing the reed D, so that the air passing through the cell 0 andthrough the reed D into the opening B produces a tone. The front end ofthe cell 0 is ordinarily closed by a valve or stop E, connected by a rodF, with the usual organ mechanism under the control of the operator, soas to open or close the front end of the cell 0. As illustrated in Fig.2, a series of such cells C is arranged one alongside the other and allare controlled by the same valve or stop E.

Above each cell 0 is arranged a second cell G in communication with thelower cell 0 by an aperture II, formed in the top of the cell 0, whichtop at the same time forms the bottom of the upper cell G. The front endof the cell G is adapted to be opened and closed by a valve I, similarto the valve E and connected by a rod .I, with the organ mechanism underthe control of the operator, so that the valve I can be opened or closedindependently of the valve E. As shown in Fig. 2, the valve I controls aseries of upper cells G similarly to the valve E controlling the likenumber of lower cells C. A spring L, is connected with the valve I tohold the same normally in a closed position and a similar spring K, isconnected with the valve E to close and hold the same closed, when notopened by the rod F at the will of the operator. Thus, ordinarily, bothvalves E and I are closed. Now, when the upper valve 1 is opened by theoperator, then the air passes through the front end of the cell G intothe latter and through the aperture II into the lower cell 0 through thereed 1) into the opening B, by the suction of the bellows,whereby aclear pure pipe tone is produced. Then the upper valve I is closed, andthelower valve E is opened by the operator, then the air passes into thecell 0 through the reed D into the opening B whereby a soft pipe tone isproduced. When both valves E and I are simultaneously opened, then theair passesinto both cells G and O, and the air in the cell G passesthrough the opening II into the cell 0 to reinforce the air entering thelatter, the total amount of air passing through the reed D into theopening B, by the suction of the bellows, whereby a pure, clear, strong,common reed organ tone is produced. Thus, the operator can at will,produce any desired tone according to the piece of music to be executed.As will be readily understood, the operator can at will change the toneas above described by opening either one of the valves E or I or bothsimultaneously, for the purpose set forth.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. An organ provided with two connected cells,an independent valve for each of the cells and adapted to open each cellat its front end to the outer air, and a reed held in one of the saidcells in such a manner as to be sounded on opening either or both of thevalves, substantially as shown and described.

2. An organ provided with two cells open at the front and located oneabove the other and in communication one with the other, the lower cellcontaining a reed and each cell containing, at its front end, anindependent valve, substantially as shown and described.

An organ provided with two cells open at the front located one' abovethe other and in coininui'iication one with the other, a reed arrangedin the bottom of the lower cell over the opening in the sounding board,and a spring pressed valve for the front open end of each cell and underthe control of the operator, substantially as shown and described.

4. In an organ, the combination with a sounding board having a series ofreed apertures, of a series of cells arranged on the said sounding boardand each containing a reed over the corresponding reed aperture in thesounding board, a valve for opening and closthe first-named series ofcells, substantially 20 as shown and described.
